BTC´s (alkyl) polyalkylene glycol (PAG) types are derived from synthetic feedstock like alkylene oxides (EO or PO). DEFINITION Polyvinyl alcohol (PVA)-polyethylene glycol (PEG) graft co-polymer is a graft copolymer of ethylene glycol and vinyl alcohol consisting of approximately 75% vinyl alcohol units and 25% ethylene glycol units. It is made up of a main hydrophobic chain of polyoxypropylene bordered on each side by two hydrophilic chains of polyoxyethylene. The term polypropylene glycol or PPG is reserved for low to medium range molar mass polymer when the nature of the end-group, which is usually a hydroxyl group, still matters. DOT 3 is made by blending polyalkylene and ether, while DOT 4 is a mixture of borate and glycol. It is synthesized from butanol, propylene oxide and 40 ethylene oxide.
